Abstract

A kind of three space target structure based on four linear TDI-CCD (Time Delay and Integration CCD) cameras is put forward to measure the target-hitting parameters and to obtain the vertical target dispersion for barrage weapons when multiple projectiles hit the target at the same time. With measurement, two CCD cameras intersect to form the vertical target I, and the target surface is perpendicular to the scheduled ballistic direction. Target surface II and III are formed by a CCD camera respectively, and a certain angle between target I and II is formed in vertical direction, which is the same as that between target I and III in horizontal direction. Combined with the geometry of three dimensional target surfaces, the imaging time and imaging angle of the flying projectile on the four linear CCD cameras, the vertical target coordinate and projectile's flying speed are calculated. Meanwhile, based on the relationship of imaging position and the constraint of flying velocity among three target surfaces, the space-time distribute parameters of multiple projectiles are deduced, such as target-hitting sequence, velocity, nutation angle and the target coordinates. Simulation and experiment show that the matching rate of multiple targets among three target surfaces reaches to 100%. The test method effectively eliminates the false target-hitting coordinate when multiple projectiles impact the target simultaneously and calculates precisely multiple projectile parameters all at once.
